CHARLES E. SACKETT, OF DANBURY, CONNECTICUT.

HAT-BRIM PRESS TO FORM \VELT EDGES.

To all whom it may concern:

Be it known that I, CHARLES E. Saonn'r'r, a. citizen of the United States, residing at Danbury, in the county of Fair-field and State of Connecticut, have invented a new and useful Improvement in Hat-Brim Presses to Form lVelt Edges, of which the following is a specification.

This invention relates to a mechanism for reinforcing the edge of a hat brim by doubling the felt back upon itself to form a welt. On the 27th day of April, 1908, I filed application Serial No. 429,425, for an invention having the same, title and purpose. That invention related to a machine adapted to form the welt edge on only one size of hat, it was operated by hand-levers, and although the general principles of act-ion are the same, the object of this invention is to construct a machine driven by power, adapted to all sizes of hats, to make the action principally automatic, and especially to provide a cutter known in the trade as a rounding jack, adapted to cut the rounding from any size of hat after the welt is formed. In application Serial No. 429,425, the cutter was fixed operating by direct pressure; in this invention the cutter is movable, operating with the drawing out peculiar to hand rounding jacks.

Heretofore in rounding jacks operated by hand, the periphery of the crown of the hat forms the guide for the cutter on the brim. In some cases where machine rounding is done, a templet located above the crown guides a cutter moving around the brim. In this invention the cutter is guided at the very point where the cutting is done which makes it positive in its action.

The general principles of the invention having been fully described in the application referred to, this specification will be confined to the improvements peculiar to this invention.

In the accompanying five sheets of drawings, where parts are duplicated on the same sheet, only one set of parts or section will be indicated by the numerals.

Figure 1, is a front elevation of a four section machine. Fig. 2, is an end view. Fig. 3, is a vertical section through line A of Fig. 1. Fig. 4, is a two section partial plan view. Fig. 5, is a detail view on an enlarged scale of the starting-lever and automatic stop motion. Fig. 6, is a detail view on enlarged scale of the counterbalance Specification. of Letters Patent.

weight levers. Fig. 7, is a plan view on enlarged scale of a four arm central rounding jack pivoted above the punch bridge. Fig. 8, is a section on line B, through Fig. T. Fig. 9, is a. section through the punch bridge on line C of Fig. 7, the rounding jack being removed from its pivot. Fig. 10, is a section on a line similar to line C of Fig. 7, the bridge carrying no punches, and a single arm rounding jack being pivoted to swing below the bridge. Fig. 11, 011 Sheet 3, is a.

single arm rounding jack adapted to travel on the platen-ring as a track, where a punch bridge is not required. Fig. 12, is a h'ori zontal enlarged detail view of the vertical moving cam roller on central line D, of Fig. 1, the counterbalance levers, guide-rods and cam being removed. Fig. 13, is a vertical view of the same, the counterbalance levers, guide-rods, and cam being shown in position. Fig. 14, is a vertical side elevation of the cam. Fig. 15, is a front elevation of the cam with clutch and shaft section, on central line E, of Fig. 1.

In all the drawings like numerals relate to like parts.

1 is a suitable frame adapted to combine the several sections of different hat sizes in one harmonious machine.

Hat sizes differ in diameter by one eighth of an inch only. The sections are all constructed alike, the difference in construction as between only two sections being limited to the diameters of the press platens only, and in drawings of the scale shown, such difference is not perceptible.

2 is a raised oval platform whose outer periphery corresponds to the periphery of a single size of hat brim; it is cast with the table plate 3, and then bolted to the frame, or it is cast separately for convenience in turning, and then bolted to the table plate; in the center'of the oval platform is a recess 4, designed to receive the crown of a hat, (see Fig. 4 and enlarged views 7 to 10).

6 is a movable ring platen having a depending flange with an inner vertical periphery 8, corresponding to the outer periphery.

of the raised platform which it closely surrounds in its descent, and having a horizon tal pressing face 9, at right angles to face 8, which impinges upon the raised platform with pressure, when a hat brim is inserted. The pressing face of the platen is made the desired width of the reversed welt-edge; any excess of felt extending beyond it has to be removed. In application Serial No. 429,425, I provided a fixed circular vertical knife for this purpose. In this invention I provide a movable rounding cutter constructed as follows. The descending platen 6, is provided wit-h a bridge 5, which crosses its internal space centrally and is secured to it by being bolted to the overhead lugs 7, projecting from the side boxes; all of which are firmly attached to the descending ring platen by suitable bolts. The bridge carries punches 10, (see Figs. 7 to 9) which punch eyelet holes in' the hat brim on the descent of the press, as these punches obstruct the annular space within the ring platen, and are not always required, I show three constructions of rounding arms provided with cutterheads, whose working face and action are the same in all, (see Figs. 7 to 11).

In Fig. 7, is shown a rounding jack, composed of four arms 11, united at their center, and pivoted upon the fast pivot 12, fixed in the bridge support, they are retained in position to revolve horizontally by the nut 13, and washer 14; each arm is provided at its end with a yielding cutter-head 15, recessed on its face bearing against the vertical inside face of the-platen ring, for the insertion of vertical knives 16, the head is split, and the knives clamped by means of the clamp screw 17. Back of the cutter-head (see Fig. 8) is a piston moving below the arms in boxes 18, 19, the piston has a shoulder 20, bearing against a spring 21, which thus holds the cutter-head yieldingly against the platen inside periphery and causes the knives to track with its contour. To one or more of the arms is attached handles 22 by means of which the rounding jack is revolved. The cutter heads are arranged in pairs to right and left of the arm ends so as to cut beneath the bridge ends 61, which are left open for that purpose (see Fig. 9) the bridge punches enter corresponding sockets in the raised platform 2. In Fi 10, is shown a bridge 5, without punches to interfere with the revolution of the ack; here a single arm 11, is shown provided with a single cutter head of the same construction as above, to swing below the bridge, the arm is keyed to the loose pivot 12, at 23, below the bridge, and the handle 22 to operate it, is keyed to the pivot at 24, above the bridge. In Fig. 11 (Sheet 3) is shown the platen ring 6, in section without any bridge; here the rounding jack consisting of a single vertical cut- ;ter-head, is constructed to travel around the top of the ring platen usmg it as a track 25,

it being faced and the jack recessed for that purpose; it is operated by the handle 22, pushed by the hand; either of these arrangements of cutter-heads will cut the welt edge true to the inner periphery of the platen ring when revolved; each ring is provided with its own rounding jack. The platen rings are provided with boxes 26 made fast to them at both sides; guide rods 27 pass through the boxes, and are firmly attached to them by set screws 28; the rods have a vertical movement in the frame by means of the over and under longitudinal cross bars 29, which are perforated at proper points to form boxes 30, in which the guide rods slide (see Figs. 1 to 4). Midway of the frame (see end view Fig. 2-) and supported by its cross section 31, are boxes 32, in which is journaled a main driving shaft 33, carrying centrally under each press sec tion a cam 34, which serves to lower the ring platen 6, and to exert pressure upon it; the cam operates against a movable roller 35, which is journaled at each end in boxes 36, also made fast by set screws 37, to the guide rods 27, at each side of the central section of the roller upon which the cam bears are shoulders 38, which serve to keep the cam in position as it travels loose upon the driving shaft; the cam has a clutch hub 39, (see Fig. 1, and detail views 14, 15) which re isters with. a corresponding clutch 40, made fast to the driving shaft as to its rotary movement by the key 41, but having a sliding horizontal movement upon the key permitting the opening and closing of the clutch jaws when operated by the clutch pin 42, made fast in the starting lever 43, at its circular section which surrounds the clutch, (see detail Fig. 5) the lever is pivoted at its fast end upon the horizontal frame bar 44, at the rear of the machine, and slides at its free end upon the horizontal frame bar 45, at the front of the machine.

At a point about midway in the vertical revolution of the cam, is cast a tapered section 46, having the same diametric center, which in its revolution gradually presses against an ear-piece 47, made fast to the lever at a corresponding point; and by its taper moves the lever horizontally, thereby drawing the clutch aws apart and stopping that section of the machine automatically and at a predetermined point under pressure, while the other sections continue in motion, it being arranged that no two sections stop at the same time; this however is optional with the attendant, who after placing a hat upon the raised platform 2, throws in his clutch and moves to the next section, and so on, the cams each make one revolution be fore stopping themselves automatically, and the hat brim remains under pressure until the operator returns, cuts the surplus rounding with the ack, and throwing in the clutch, the platen rises giving ample time for the operator to remove the hat and. replace it with another when the operation is repeated. The cams are all driven by the shaft 33, which is operated by a worm wheel 48, made fast to one end, and a worm 49, made fast to the shaft 50, which is journaled in boxes 51, on the frame of the machine, and driven by fast and loose pulleys 52, from any convenient power. The driving shafts move continuously, and the main shaft 33, has a slow enough motion to allow sufficient time for the changing of the hats; the rounding is effected while each section is at rest under pressure. The action of the cam only exerts pressure to force the movable roller 35, downward, and with it the press platen, the cam has no lifting power, the return or upward lift of the press platen is accomplished by means of the counter-balance levers 53, 54, (see detail Figs. 6, 12 and 13, and Figs. 1 to 4:) which are movably journaled upon the roller bearings 55, 56, of the movable roller 35, have a revolving central bearing 57, upon the horizontal round bar 58, made fast in the frame of the machine, are retained in their places on that bar by the fast collars 59, and support a weight 60, at their extremities, which slightly overbalances the weight of all the descending parts of each section. This weight is raised by the cam as it pushes the other parts downward, and the descent of the weight by its gravity returns the other parts including the press platen to their original positions.

Various changes in detail might be effected in the construction. or movement of the sections or rounding knives, without altering the general principles of my invention. I do not limit myself as to details, but
